Acute lethal poisonings in children: a 10-year retrospective study of the Moscow Region, Russia

Journal of Public Health Research, 2021
Background: Poisoning is a critical public health problem. Toxic substances differ across time, region and age. Little is known about poisoning in Russia, and even less is known about lethal poisoning in children in Russia.

Carbon Dioxide in Exoplanetary Atmospheres: Rarely Dominant Compared to Carbon Monoxide and Water in Hot, Hydrogen-dominated Atmospheres [PDF]

, 2015
We present a comprehensive study of the abundance of carbon dioxide in exoplanetary atmospheres in hot, hydrogen-dominated atmospheres. We construct novel analytical models of systems in chemical equilibrium that include carbon monoxide, carbon dioxide, water, methane and acetylene and relate the equilibrium constants of the chemical reactions to ...

The Diagnosis and Treatment of Carbon Monoxide Poisoning.

Deutsches Ärzteblatt International, 2018
BACKGROUND The symptoms of carbon monoxide (CO) poisoning are nonspecific, ranging from dizziness and headache to unconsciousness and death. A German national guideline on the diagnosis and treatment of this condition is lacking at present.

Chemical Bonds Containing Hydrogen: Choices for Hydrogen Carriers and Catalysts

Angewandte Chemie, EarlyView.
Hydrogen carriers utilizing B─H, C─H, N─H, and O─H bonds are evaluated for their potential in hydrogen storage and release. Key candidates such as methanol, ammonia, and formic acid are examined with a focus on critical factors influencing performance, including the nature of chemical bonds, reaction pathways, and catalytic processes.

Cerebral Damage after Carbon Monoxide Poisoning: A Longitudinal Diffusional Kurtosis Imaging Study

American Journal of Neuroradiology, 2019
BACKGROUND AND PURPOSE: Previous DTI cross-sectional studies have showed the cerebral damage feature was different in the three clinical stages after carbon monoxide poisoning. Diffusional kurtosis imaging (DKI) is an advanced diffusion imaging model and

The applications of single‐atom alloys in electrocatalysis: Progress and challenges

SmartMat, Volume 4, Issue 1, February 2023., 2023
Single‐atom alloys (SAAs) with peculiar electronic structures, well‐defined active sites, and maximum atom utilization are promising to replace traditional noble metal electrocatalysts. Representative strategies to prepare SAAs including wet chemistry, galvanic replacement, dealloying, and atomic layer deposition are introduced.

Direct Observation of Electron Donation onto the Reactants and a Transient Poisoning Mechanism During CO2 Electroreduction on Ni Single Atom Catalysts

Angewandte Chemie, EarlyView.
In situ techniques reveal key insights into the electrochemical reduction of CO2 on Ni single atom catalysts. Through poisoning studies, we reveal that the reduction of the system does not result in a metal‐based reduction, rather it is associated with donation of electrons onto a combination of the support and the reactants.
